Discounting the colour around them, the right picture has more of an impact I think. Easier to read Anker on the side and the lighting coming from the top highlights the ports, carbon effect surround and the branding all at the same time. The lighting on the left picture only really highlights the carbon effect.

The color red is more tentative so your eyes are naturally drawn to it. Either picture would work with the red background, but I chose the right in because it details more of the charger. It shows both charging tans and the button on the bottom, highlights the "Anker" name and shows the carbon fiber texture much better than the one on the left

I voted for the picture on the right. This is probably going to sound weird, but looking at each picture, my eyes naturally go from left to right, it's a more natural feel for my eyes to move upward as opposed to down. Just a more natural feel.

I think you need to make a mix of the two pics. In my opinion the orientation of the charger in the right one is better, but blue is the color of the Anker company and from a psicological view blue is the color of trust.Hope to be helpful

Went with the left since the first I look at when it comes to the product is ports. I already know what brand I want so having the brand be the center of attention wasn't necessary. Also the blue was more pleasing to the eyes and looked more like the brand color compare to red.
